It looks like I spoke too soon.  I have the DSDT only, most of them
already piped through the disassembler :(   These came from the old
ibm-acpi maintainer, and also from acpi.sf.net.  Neither Borislav nor
acpi.sf.net saw the value of storing the full set of ACPI data
structures.

I know better, but I have the full acpidump+dmidecode for just a few
thinkpads, and I have not organized it properly in one place, yet :(
I am sure the r40e and r50e were not on the set, though.

Well, since ltp is already CC'ed, they can help us get the data we need.
I will send a more attention-catching request as a reply to this.
